To increase or decrease the amount of anti-skating force applied, simply unplug
the Lemo connector and twist it in the direction you want the force applied.
For example, to increase anti-skating force give the connector a
counterclockwise twist, unwinding the coiled wire. Likewise, to decrease the
force, give the connector a clockwise twist. Remember, the Lemo connector
can only be "adjusted" in increments of whole turns. If it is not, its key will not
line up with the groove in the receptacle.
We could go on discussing the pros and cons of how much anti-skate is correct,
but the sonic answer is very simple. Adjust the wire as mentioned above until
the tonearm drifts outward when set to neutral balance. When you push the
neutral balance floating tonearm towards the center of the record, it should
push back out towards the rim of the record. Very little force is needed to do
this, and the wire acts like a spring to supply this force.
If you try adjusting the anti-skate with a groove less record or a test
record you will ruin the twist in the wire and void your warrantee
Double check the horizontal balance, lateral balance, and tracking force and
adjust as needed. Increase the tracking force by 1/10 of a gram above the
cartridge manufacturers highest recommended force.

ARM HEIGHT:
NOTE: THE TWO THUMBSCREWS MUST BE RELEASED WHEN MOVING THE
VTA KNOB. THE THUMBSCREWS SHOULD BE TIGHTENED WHEN LISTENING.
Unlike many tone arms, the JMW's height is both easy and repeatable to vary. The
knob next to the bearing housing bears a scale numbered from zero to ninety-nine.
Below the knob there is an index mark engraved on the front of the support pillar.
Rotating the knob clockwise lowers the arm and rotating it counterclockwise
raises it.
Set the arm height as follows:
Place a record on the platter surface. Lower the arm onto the record and make
the arm tube parallel to the record surface by rotating the arm-height knob as
needed.
This is a good initial setting. You may wish to vary it depending on the
